Sash-fastener



UNITED STATES 'PATENT 'OFFICEo JEROME B. KES'IER, OF GLARIISBURG, WEST VIRGINIA.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent N o.Y 377,522, dated February '7, 1888.

Application filed September 9, 1887. Serial No. 249,254. (No model.)

-To all whom, it may concern:

Be it known that I, JEROME BONAPAETE KESTER, of Clarksburg, in the countyof Harrison and State of West Virginia, have invented a new and Improved VVindoW-Sash Fastening, of which the following is a full, clear, and exact description.

My invention relates to fastenin gs for locking upper and lower sashes closed or open to any desired extent in the window-frame; and lthe invention has for its object to providea simple, inexpensive, and effective device of this character.

rlhe invention consists in certain novel features of construction of the sash-fastening, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

4in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is an insideface view of a windowframe and upper and lower sashes therein with my improved fastenings applied to the sashes and with the window-frame partly broken away and in section. Fig. 2 is a vertical sectional side view thereof, taken on the line x x, Fig. I. Fig. 3 is a plan view in section on the line y y, Fig. l; and Fig. 4 is a detail plan view taken on the line z z, Fig. l.

Ths window-frame A and upper and lower sashes, B C, may have any approved construction. The frame is shown with the ordinary stop-bead, D, at the inside of the lower sash and with the usual parting-strip, E, between the sashes.

The fastenings for both the lower and upper sashes embody thesame principles of construction, but differ somewhat in form to adapt them to their respective s ashes, as I will hereinafter explain. I will more particularly describe the invention .with reference first to the fastening on the lower sash, and as follows:

In its preferred form the sash-fastening consists of three main parts-a metal plate, F, which is attached by screws or otherwise to the inner face of thesash, a metal latch-bar, G, pivoted at g to the plate F, and a metal lock-bar, H, pivoted at h to the plate F. The latch .G has a right-angular general form, and its shortarm g is adapted to enter anyone of a series of notches, I, made in the adjacent vthe side of the window-frame.

stop-bead D, and the long arm g2 ofthe latch is provided at its free end with a shoulder, g3, I

onto which the free end h of the lock H rests or overlaps when the parts are in normal positions. Astopfpin, J, in the plate F limits the swinging movement of the latch G towar To the lock H is txed one end of a wire bridge or staple, K,which passes over the face of the latch G, and at its extremity is bent inward to form a catch or pull, k, which normally stands off sufficiently from the latch G to allow the lock Hto be swung sidewise by 'l pressing' its knob h2 until the end h of the lock clears the shoulder gs of the latch, whereupon the catch k will, by contact with thelatch G, swing it away from the frame A and withdraw its arm g from the notch I of the windowframe, as indicated in dotted lines in Fig. l of the drawings, and the sash may then be slid up or down freely; but when the lock H is let go or released from the hand the parts G H willswing downwardby gravity, and as the latch G strikes the stop J and enters a notch I the lock H will swing in over the shoulder g3 of the latch G, and will lock it into the notch I of the window-frame until the lock H is again swung sidewise clear of the latchshoulder g3, as will readily be understood.

The fastening for the upper sash is like the lower one, except that the arm g of the latch is at thelower end of it instead of at the upper end, and the operation of the upper-sash fastening is precisely similar to that of the lowersash fastening, except that the latch-arm g' enters a notch I made'in the parting-strip E instead of the stop-bead D.y The knob or button hof the lockY H of the upper fastening is made short or dat to allow the lower sash to pass over it or allow it topass behind the lower sash as the sashes are moved in the windowframe.

The main plate F is not essential to the successful operation of my'inventiomas the parts G H, or G, H, and K, which are its principal features, would operate successfully were they connected directly to the facesof the sashes;

but the advantages of the plate Fare so obvious in allowing proper adjustment of the parts kand easy connection of them to the sashes that the main plate cannot well be dispensed with.l

ICO

Having thus described my nvention,what I claim as new, and desire to secure by Letters Patent, is-

l. A window-sash fastening comprising a gravitating latch pivoted to the sash and adapted to a notch or detent at the windowfranie and provided at ils pendent part with a shoulder, a gravitating lock pivoted tothe window-sash and adapted to overlie thelatchshoulder, and a bridge or catch on the lock allowing it to be withdrawn from the latchshoulder before acting on the latch to l disengage it from the window-frame, substantially as herein set forth.

2. The combination, in a sash-fastening, ofa plate, F, agravitating latch, G, pivoted thereto and having an arm, g', adapted to a notch or detent at the window-frame, and provided also with a shoulder, g3, a lock, H, pivoted to the plate F and adapted to the latch-shoulder g3, and a bridge, K, having a catch, k, allowing the lock to be disengaged from the latchshoulder before disengagin g the latch from the window-frarne,substantially asherein set forth.

3. In a windowsash fastening, the combination of a gravitating latch, Gfpivoted to the sash and provided with an arm, g', and a shoulder, g, a lock, H, pivoted to the sash and adapted to thelatch-shoulder g3, abridge, K, held to the lock and having a catch, k, allowing the lock to be disengaged from the latch-shoulder before disengaging the latch from the window-frame, and astop, J, limiting the movements ofthe latch and lock, substantially as herein set forth.
